Abstract
Structures for a silicon-controlled rectifier and methods of forming a structure for a silicon-controlled rectifier. The structure includes a first well and a second well in a semiconductor substrate. The first well has a first conductivity type, and the second well has a second conductivity type opposite to the first conductivity type. The structure further includes a first terminal having a doped region that has a portion in the first well, and a second terminal including a second doped region that has a portion in the first well and a third doped region in the second well. The first and second doped regions have the second conductivity type, the third doped region has the first conductivity type, and the second doped region is positioned in a lateral direction between the first doped region and the third doped region.
